Muon g-2 Experiment Pioneers Win Breakthrough Prize in Fundamental Physics

The Muon g-2 Collaborations at CERN — the European Organization for Nuclear Research — and two U.S. Department of Energy National Laboratories — Brookhaven National Laboratory and Fermi National Accelerator Laboratory (Fermilab) — are the recipients of this year’s Breakthrough Prize in Fundamental Physics. Over a period of more than 60 years,...

Call for Photo Submissions: Support the AIP Visual Archives

AIP is working to enrich Niels Bohr Library & Archives collections by improving the documentation of women and underrepresented people in the physical sciences. They collect visual documentation of the personal and professional lives of physical scientists. Their collection contains images of modern American physicists, astronomers, geophysicists and many other kinds of scientists. In general, they...

BASE Experiment at CERN Succeeds in Transporting Antimatter

Today, in a world first, a team of scientists from the BASE experiment at CERN successfully transported a trap filled with antiprotons in a truck across the Laboratory’s main site. The team managed to accumulate a cloud of 92 antiprotons in an innovative portable cryogenic Penning trap, then disconnect it from the...

By Phillipp Bircher With the appointment of Dr. Barbara Frei-Spreiter, RUAG International concludes the multi-stage search process to succeed André Wall as CEO of RUAG International and its space business, Beyond Gravity. Dr. Barbara Frei-Spreiter is a proven Swiss executive with over 25 years of international leadership experience in global...

Solving a Mystery in Dark Matter Detectors Could Improve Quantum Computers

By Lauren Biron Although dark matter makes up most of the mass in our universe, it has never been directly observed. To hunt for lighter dark matter and other rare phenomena, researchers must solve a puzzle in their supersensitive detectors: an unexpected number of low-energy events, called the “low-energy excess”...

How Argonne’s Aurora Supercomputer Is Opening up New Horizons for Fusion Energy Research

By Christina Nunez If you could build a star on Earth and harness its abundant energy, you’d need to know exactly how to store the star and keep it stable. Fusion energy scientists have been working for decades to make the idea a reality. They now have a potent new tool at...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Searching for a company to make a specific kind of cryogenic chamber

I am writing a proposal to do some deep space simulations of mechanical vibrations at cryogenic temperatures. For the research, I will need to obtain a chamber that has a space of approximately 1700 cubic inches (or a 12in. cube) that also has an optical viewing window.
